Prospective cohort study. ⋯ The MCID for the 6WT in lumbar DDD patients is variable, depending on the calculation technique. We propose a MCID of 92m (z score of 1.0), based on the average of all three methods. Using a z score as MCID allows for the standardization of clinically meaningful change and attenuates age- and sex-related differences.Level of Evidence: 3.

A retrospective study. ⋯ Posterior decompression relieves LBP as well as leg pain. Long-lasting LBP and concurrent symptomatic cervical myelopathy are important predictors for inadequate LBP relief. There were no reliable imaging parameters predictive of inadequate LBP relief.Level of Evidence: 4.

Retrospective cohort study. ⋯ After carefully eliminating patients with segmental instability, DS did not affect the clinical outcomes of minimally invasive decompression surgery.Level of Evidence: 3.

Observational Study
Subjective and Objective Change in Cervical Spine Mobility After Single-level Anterior Cervical Decompression and Fusion.
Prospective, observational study. ⋯ The concern of many patients of being severely restricted in their cervical spine mobility after single-level ACDF can be denied. Objectively, the rotation even showed a significant improvement. Regarding the subjective restriction, which is more important for the patients, we found a significant improvement in general and for all directions of movement after surgery.Level of Evidence: 3.

Retrospective review. ⋯ Centers for Medicare and Medicaid Services only considers HCAHPS surveys returned within the first 42 days. It appears that the survey responses are similar over this time period. Beyond this time, lower scores are reported. Further attention to this less satisfied, later HCAHPS survey returning group seems warranted.Level of Evidence: 2.
